METAL-SHIEATHIED PANELEID PARTITION.

Patented Nov. 26, 1907.

Application filed August 21. 1905. Serial No. 275.145.

salient ob ects of the present invention are to provide a construction in which cealed: to

ordinary finishing lumber or mill work, as it is commonly termed, is em loyed to form the partition frame and t 's frame structure is so covered by sheet metal as to provide a reliably fire-proof structure; to provide a construction which may be very economically manufactured and at the same .time. permits of the formation of molding edges,angles, beads and analogous ornamentatlon, enabling the structure to closely simulate woodwork', to provide a construction which may be very conveniently assembled and'in which the framemembers are united at their points of intersection in an extremely strong, efficient and simple manner and in which the unitin mechanism is entirely conrovi e a construction which ermits of building up into panels and openings of various sizes and shapes with convenience; to provide an improve manner of supporting or anchorin the partition structure to the floor and cei ing structure so that access of fire to the interior of the frame Work structure by the burning of the ceiling or floor is prevented; and in general to provide imrovements in the detail of the character reerred to. a

To the above ends the invention resides in the matters hereinafter described and more .of one o the dowel-bolts and nut.

tion of the parts shown in Fig. 2. Fig. 4 is a horizontal sectional view taken on line 4-4 of Fig. 2. Fig. 5 is a sectional view taken on line 5-5 of Fig. 2 and looking in the direction of the arrows. Fig. 6 is. a vertical sectional view throu h the central portion of the lower end .0 one of the upright frame members, showing the construction and arrange ment of the anchor plate and the manner in which the latter is united to the upright and floor res ectively. Fig. 7 is a sectional detail Fig. 8 is a fragmentary view of the meeting. edges of the sheathing.

Referring to the drawings, 1, 1 designate'a series of upri hts and 2, 2 and 2 a series of cross rails; t ese members in the finished structure serving to separate the partition into panels and openings.

The uprights and cross rails are severally of the same general construction. That is to say,'each frame member is composed of four strips or casing members, as 3, 3 and 4, 4 respectively, arranged to form a hollow supporting frame member, internallyrectangu-- the strlps going to make up any articular frame member have been assemble In the construction illustrated, the members 4 and 4. are sufliciently less in width than the external width of the box structure to provide rabbets 7 at the four external angles of the frame member and accordingly the sheathing members are suitably shaped to fit these angles and have their edges 8, 8 arranged to meet along lines a proximately coincident with the middles of the strips 3 and '3, as seen clearly in Fig. 4. These sheathing members may be utilized to hold the frame strips in proper assembled relation and to this end, an in order to secure the sheathings in place, their edges are. tacked or nailed to the underlying strips 3 and 3 at suitable intervals apart as indicated at 9.

Suitable moldings as indicated at 10, v10' and 11, are applied to the box frame; the first mentioned serving the function of su porting the panels while the strip 11, in t e the metal being suitably formed into hollow channel-like cross sectional form and the molding so applied that the edges, as 12,12 and 13, 13 rest against the outer faces of the metal sheathings.

As an improved detail of construction, the moldings are so punched as to form countersunk apertures 14 which permit securin screws 15 to be inserted therethrough an into the under lying frame structure, with their heads flush with the-outer surface of the molding. As an improved means of uniting the several frame members at their points of intersection, each abutting member is provided with a plurality of. securing bolts 16, seated in' the opposed side members and projecting therefrom so as to form in effect dowelins, which extend through the proximate si e of the upright. Describing this construction more in detail, and referring more particularly to Figs. 2 and 4, the upper and lower side members 4 and 4 are bored longitudinally toreceive the lengths of the bolts 16 and atthe inner end of each bolt aperture, they are cross bored, as indicated at 18, to receive nuts 19. The nuts 19 are of special form, which enables them to be seated in round apertures and when thus seated reliably anchor the dowel-bolts. To this end'each nut is of polygonal form and has its angles seated in the sides of the cross-bore 18, and a threaded a erture 19 which receives the corresponding y threaded end of the bolt, extends transversely through one side of the nut and into its central opening, as indicated clearly in the detail sectional view Fig. 7..

, this plate being desirably of the exact size and configuration, as to its margins, of the outer con guration of the abutting member and bein apertured for the passage of the dowel-b0 ts therethrough. Inasmuch as the abutting member must be secured in position at a time when access may be had to the interior of the abutted member, the mar ins of the plate 21 are provided with very s allow but extended rabbets 22 which permit the sheathin s 5 and 6 of the abutted mem.

her to be a justed to osition to envelop said member after the a utting member has frame members at their ends, as for example where they rest u on the floor or engage the ceiling or side wa ls, I have provided an an chor plate of special construction. Referring to Fig. 6, 24 designates as a whole one of these anchor plates which in plan, size and configuration, conforms to the frame member it is designed to support. One side 25 of the plate is usually made flat to rest against the cor or wall and u on its opposite side the iplate is provided with ribs 26 constructed to t and telescope within the end of the frame member. The plate is suitably secured to the frame member, as for example by means of screws inserted through the ribs 26 and into the frame structure, as indicated at 27, and the whole structure united to the floor or wall by means of an anchor bolt 28 which maybe a wood screw or other suitable bolt. An important characteristic of the present invention is that the parts are so constructed and arranged that they may be conveniently assembled and anchored in position Without leaving any exposed securing devices to disfigure the structure. bling and securing the structure in position,

three sides of each of the abutted members are first assembled in proper relation and the sheathing of that side applied and secured so as to hold these parts assembled. The abutting members are next placed in position and their dowel-bolts inserted and screwed home. The anchor plates having been suitably secured in the ends of the partially assembled abutted members, the structure is placed in position in the building and suitably anchored by the insertion of the bolts 28.

The fourth side of the .abutted member is now placed in position and the sheathing of that side applied'and secured; it being noted that the abutting plates 21 are spaced away from the abutted member: at their edges so as to permit the sheathing to be applied. The moldings are next applied,

whereupon the structure is complete 1nreadiness to receive the panels, doors or In assemother filling members which complete the 7 partition. 7

It is to be particularly noted that in a structure embodying my invention all joints of the sheathing are perfectly con cealed and as to those which are exposed to the exterior the are interlined by themetal plates so that e could not obtain access even thou h such joints should by reason of s age of'the wood, or expansion of the same under heat, slightly open. Moreover the anchor plates prevent access of fire to the low and one side thereof detachable, a divided metal envelop arran ed to inclose said abutted member, one part 0 which envelop covering the detachable side being also detachable and internally arranged connected devices uniting said abutting and abutted members.

2., In a metal covered paneled or analogous frame structure, the combination with intersecting upright and transverse frame members, one arranged to abut against the other and the abutted member made hollow and one side thereof made detachable, of a dowel bolt seated longitudinally in the end portion of the abutting member and extendmg through the proximate side of the abutted member, whereby it is accessible when assembling said parts and inclosed when assembled.

3. In a metal coveredpaneled oranalo gous frame structure, the combination with intersecting upright and transverse frame members, one arranged to abut against the other and the abutted member made hollow and one side thereof made detachable, of a dowel bolt seated longitudinally'in the end portion of the abutting member and extending through the proximate side of the abutted member whereby it is accessible when assembling said arts and inclosed when assembled and an a utting plate interposed between the end of the abutting member and the connected member.

4. In a metal covered paneled or analogous frame structure, the combination with intersecting upright and transverse frame members, one arranged to abut against the other and the abutted member made hollow and one side thereof made detachable, of a dowel bolt seated longitudinally in the end portion ofthe abutting member and extendmg through the proximate side of the abutted member whereby. it is accessible when assembling said parts and inclosed when assembled and an abutting plate interposed between the end of the abutting member and the connected member, said abutting plate being constructed to conform at its margins to the external confi ation of the abutting member and provi ed with marginal rabbets, and sheet metal envelops inclosing both abutting and abutted members.
